Title: Semiconductor device
Inventor: ITOU TAKASHI
IPC: H01L29/06
Filed: 1978-06-09
Abstract: PURPOSE: To reduce the deterioration rate of a semiconductor device by electrically providing a radical metal film onto the blank space part or surface of the insulating film on the semiconductor element surface from its circumference.  
     CONSTITUTION: On the surface of a semiconductor element, metal easy to corrode by moisture including impurities such as Al via an insulating film. When moisture sealed in a hollow container or moisture immersing is much, it becomes dew on the element surface to deteriorate characteristics, causing corrosion if the electrode is made of Al. Corrosion relates to the quantity of moisture and Al area and when the quantity of moisture is fixed, the etching speed is faster as the Al are smaller. With a little moisture, corrosion stops soon and the element function will never deteriorate. In case of a resin-sealed device, an Al thin film on an insulating film is provided to the outer circumference of the element and immersion to the element surface is reduced corresponding to the quantity of immersing moisture, so that the deterioration rate can be reduced as well as a hollow container.

Abstract: PURPOSE:To satisfy the prescribed load-tightness and thermal invasion resistance and to arrange compactly by oppositely arranging superconductive supports around the periphery of a superconductive coil on its part or on the whole, while supporting the superconductive supports with supporting legs. CONSTITUTION:Ring-shaped supporting structures divided in two, wherein a superconductor 2 of a bark material and a film is fitted, are oppositely arranged on the outer periphery and part of both sides of a superconductive coil 1 and these supporting structures 3 are mounted on a vacuum container 5 by supporting legs 4. When a current I is conducted to the superconductive coil 1, magnetic lines of force 6 are generated around the coil, while the superconductor 2 in a superconductive state has anti-magnetism so that the gap part between both gets magnet flux density B as average. At this time, repulsive force is generated between both and when this is larger than the external force acting on the superconductive coil 1, the superconductive coil 1 is maintained in a floating state. Thereby, conductive invasion heat to the superconductive coil 1 becomes zero so that the supporting legs are required only to have a sectional area securing sufficient strength and their length can be short.
